强酸型魔芋葡甘聚糖基离子交换树脂对Cu^(2+)的吸附性能研究

PERFORMANCE STUDIES ON ION EXCHANGE RESIN OF STRONG ACIDITY BY THE MATRIX OF KOJAC GLUCOMANNANAND ITS ADSORPTION PROPERTY FOR Cu^(+2)

以交联魔芋葡甘聚糖颗粒为原料,采用先羟丙基化再磺化的方法制备了强酸性魔芋葡甘聚糖基离子交换树脂。该树脂的骨架密度为0.2172 g/m l,平均孔容量为2.7446 mL/g,树脂空隙率为37.20%;交换容量为0.1445 mm o l/g,对Cu2+的吸附量为1.3855 mm o l/g。

Sulphonate Hydroxypropyl crosslinked konjac glucomannan granule （SHPCKGG） have been prepared by hydroxy-propylation and sulfonation with cross-linked konjac glucomannan （KGM）. The resin＇s skeleton density was 0. 2172 g/mL, and average hole capability 2. 7446 mL/g, void ratio 37. 20%; working exchange capability 0. 1445 mmol/g, adsorption capacity for Cu^2＋ 1. 3855 mmol/g.
